2 Timothy 3:5-9

holding to a form of [outward] godliness (religion), although they have denied its power [for their conduct nullifies their claim of faith]. Avoid such people and keep far away from them. For among them are those who worm their way into homes and captivate morally weak and spiritually-dwarfed women weighed down by [the burden of their] sins, easily swayed by various impulses, always learning and listening to anybody who will teach them, but never able to come to the knowledge of the truth. Just as Jannes and Jambres [the court magicians of Egypt] opposed Moses, so these men also oppose the truth, men of depraved mind, unqualified and worthless [as teachers] in regard to the faith. [Ex 7:11] But they will not get very far, for their meaningless nonsense and ignorance will become obvious to everyone, as was that of Jannes and Jambres.
